In this paper, we propose O-Star, a scalable optical switching architecture for on-chip many-core systems, employing hybrid mode and wavelength division multiplexing technology. The O-Star uses the Benes topology as the core switching module to reali

For chip multiprocessors, one major challenge is to bridge the increasing speed gap between processor and the global on-chip interconnect delay. By integrating optical interconnects in network-on-chip (NoC) architectures, optical NoCs can overcome th

Optical network-on-chip (ONoC) is an emerging communication architecture for manycore systems due to low latency, high bandwidth, and low power dissipation. However, a major concern lies in its thermal susceptibility - under onchip temperature variat
Optical network-on-chip (ONoC) architecture offers ultrahigh bandwidth, low latency, and low power dissipation for new-generation manycore systems. However, the benefits in communication performance and energy efficiency will be diminished by communi
